To all whom it may concern: I

Be it known that I, EDWIN G. IVAN ZANDT, a citizen of the United States,and a resident of thecity of St. Louis and State of Missouri, haveinvented certain new and useful Improvements in Gas-Burners, of whichthe following is a specification.

This invention relates to gas-burners, and more particularly to those ofthe Bunsen type, and has for its object to-produce a burner which willbring about as complete a combustion of gas as possiblein that gasandmixed with the proper supply of air.

air-mixture is ignited while passing out of the burner in a finelydivided state.

In the accompanying drawing, Figure '1 is afront view of an embodimentof my'invention. Fig. 2 is a central vertical sectional view of thesame, and Fig.3 is a fragment-a1 sectional view of a detail.

Similar reference characters indicate corresponding parts throughout theseveral views.

Referring with a mixer, whereby the gas is intimately The'burner itself'consists of two parts or members, a lower. member 6 and an upper member9. The lower member is of flaring 4 shape and has alvtflanged rim 7 atits lowerpart adapted to surround the pipe 5,and a' flan'ged rinr 8, atits upper part adapted to surround the other member 9 of the burner. Themember 6 fits snugly; around the member 9. and is so tightly clampedthereon by reason of the expansion to which the flange I is put, that noair'ma'y ass between the members. The upper mem er 9 consists of atop-plate 1 0 and a plurality of ribs 12 separated from each other byannular openings 11 'of a definite width and distance apart, whilestruts 13 bind the top-plate and the separate ribs 1 2 to ether;Thefnember 9 is preferably'made 0 cast material and in the form of a cuphaving innervertical ribs,

which'casting is then subjected to a peripheral cutting so as to providethe casting with a plurality of slots or openings corresponding to theopenings 11, the remaining material of the wall of the cup forming theribs 12 and the vertical. ribs forming the struts 13.

In the embodiment .shown in Figs. 1 and 2 the ribs 12 as also theplat'e10, are provided with inclined surfaces 15 which serve to the drawing,the pipe 5 is connected with a suitable supply of gas and' to formoutwardly-flaring or V-shaped openings and bring about thereby aspreading of the gas during its ignition. These out-- wardly flaringopenings may also be arranged as to terminate in parallel channels asshown in Fig. 3. The member 6 is preferably madeof pressed steel and itsupper flange 8 surrounds the. lowest" rib of the member 9. The member 9is of larger diameter than thepipe 5, and the member 6 is provided withan upwardly-inclined surface, so that the gas when passing out of theupper end of the pipe 5 spreads when enter ing the member 9, and themember 9 thus acts as a reservoir or gas-container prior to the ignitionof the gas. The gas is. then .caused to pass out of the openings 11 andis thus subjected to a div1s1on or spreading partly on account of theoutwardly-flaring shape of the openings 11 and at the exterior of whichshell the spread portions of gas are ignited. By thus dividing up thestream of gas into separate smaller streams, the ignited portionsthereof are capable-0f being acted upon to a considerable degree by thecombustion of the gas is secured. .The struts 13, which, in theembodiment shown in the 'drawln are $13 in number," also serve to of gasfrom the interior of the member 9 to the exterior thereof; in. otherwords, the flame is of the same intensity at all the exterior-parts ofthe member 9.

lar openings, and further in providing the interior of the openings withinner parallel channels, and in arranging the openings so as to beV-shaped, and further in'- the gas burner comprising a cup-shaped memberand a flaring lower member secured at its upper oxygen of the air, andthereby a very good 7 My invention therefore consists of an im-' 'provedburner hav ng an inverted cupshaped member provided with a plurality ofoutwardly-flaring contiguously placed annu-- part to the lower part ofsaid cup-shaped member, and lastly, in providing such a burner withvertical ribs integral with the annular ribs.

I have shown several embodiments of my invention, but I do not wish tolimit myself to the same, since changes may be made therein Withoutdeparting from the spirit of my invention.

I claim as new:

1. In a gas-burner, an inverted cup shaped member provided with aplurality of horizontally disposed outwardly flaring contiguo-uslyplaced annular openings.

2. A gas-burner comprising an inverted cup-shaped member provided with aplurality of horizontally disposed outwardly-flarshaped member.

ing annular openings contiguously placed,

and a flaring lower member secured at its wider part to the lower partof said cup- 3. A gas-burner comprising an inlet-pipe,

a one-piece inverted cup-shaped memberhaving vertical ribs on the innerface of the walls of said member, said walls being pro- 1 vided with aplurality of horizontally disposed outwardly-flaring openings, wherebyoutwardly-tapering annular ribs are formed integral with said verticalribs, and an upwardly and outwardly flaring lower member provided withupper and lower annular flanges shrunk upon said cup-shaped member andsaid pipe respectively.

4. In a gas-burner, an inverted cup-shaped member provided with aplurality of V- shaped contiguously placed annular openlngs.

5. In a-gas-burner, an inverted cup-shaped member provided with aplurality of outwardly-flaring contlguously placed annular. openings,the interior of said openings terv minating in parallel channels.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two subscribing witnesses.
